Abstract

A quality-of-service (QoS) aware scheme, called precautionary performance monitoring, is proposed to solve the optical impairments and congestion control in coherent optical orthogonal frequency division multiplexed (CO-OFDM) networks. The centralized path computation element (PCE) extensions based on the QoS level are applied to optical performance monitoring in this letter.
